Spa Filter Cover

This is a cover you can put on the filter of your Coleman/Saluspa inflatable hot tub to allow you to attach a length of flexible pipe to it. This lets you use the pump and filter to vacuum out any debris that gets into your "hottube" (our name for these little inflatable tubs)

Designed in TinkerCAD, this is not a beautiful or complicated build but works really well to get grit out of the water. You may need to edit it (https://www.tinkercad.com/things/7enAmyY64IR) to adjust to the size pipe you have (or can buy at your local hardware store). My pipe came from the sump-pump section.

You do need to rotate it 180º when slicing (it was easier to design that way)

When slicing in Cura I checked "Generate support" but also changed "Support Placement" to "Touching Build plate" (otherwise the whole pipe ends up full of supports which are super hard to remove!). Other than that all defaults were used.
